拔长
也称延伸,它是使坯料横断面积减小、长度增加的锻造工序。拔长常用于锻造杆、轴类零件。
自由锻造的基本工序包括镦粗、拔长、冲孔、弯曲、扭转、错移、切割及锻接等。
Pulling length
Also known as elongation, it is a forging process to reduce the cross-sectional area of the billet and increase the length. Pullout is often used in forging rods and shaft parts.
The basic processes of free forging include upsetting, drawing, punching,锻造, bending, torsion, offset, cutting and forging.
自由锻造所用工具和设备简单,通用性好,成本低。 同铸造毛坯相比,自由锻消除了缩孔、 缩松、气孔等缺陷,使毛坯具有更高的力学性能。锻件形状简单,操作灵活。
Free forging tools and e are simple, versatility and low cost. Compared with the casting blank, the free forging eliminates the defects such as shrinkage porosity, porosity,圣霖锻造哪家好, porosity and so on,锻造报价, so that the blank has higher mechanical properties. The shape of the forgings is simple and the operation is flexible.
二十世纪60年代以后,锻造机械改变了从19世纪开始的,向重型和大型方向发展的趋势,转而向高速、高效、自动、精密、专用、多品种生产等方向发展。
After 60s twentieth Century, forging machinery changed the trend from nineteenth Century to heavy and large direction,圣霖锻造型号, and turned to high speed, high efficiency, automatic, precision, special, multi variety production.
